Grub Issue ?

[nealaustin]

Yesterday I upgraded loaded 11.10 onto a windows machine as a dual boot. I did change the grub to pause for only 3 seconds. Then I also installed all of the updates. Today I decided to upgrade to 12.04 but all I get is:

[ 31.537714][drm:drm_crtc_helper_setconfig] *ERROR* failed to set mode on[crtc:6]

and when I press enter then I get the command prompt. What can I do to to get to the desktop?

thanks for your help kc1. I did get past the error messages. but to no avail.The computer continues but wouldnt load compiz. I could get to the settings for the video card but not much else. somehow at the reboot the comuputer failed to set mode on crtc6. It's funny that this happend only in 12.04 (32). It happened from a clean install, an upgrade from 11.10, a dual boot install then upgrade from 10.10, and a dual boot from 12.04. I even tried all of the above with a new CD from a different mirror. I have now done a fresh install with 11.10 (32) and am leaving it there. Maybe in 1 or 2 rears I can buy an new system 76 computer. (It's my wife's 6 year old computer and a new one would make a good birthday present)

Well it could be that it's just too old for 12.04. But I would like to know what the video card is in it. As there have been problems with Nvidia cards and 12.04.

[nealaustin]

Yep it's a Nvidia and it uses the 173 driver. Even the 11.10 won't tell tell me which one it is. I can't find the manual anymore.

That may be part of the problem your having with 12.04 as there is a but that affect some Nvidia cards.

Good luck,

If not GeForce 6 or 7 then you may have just needed nomodeset.
